Wireless communication system using joint detection to compensate for poor RF condition based on user priority

Abstract

A wireless communication system including a carrier network, a network application server coupled to the carrier network, and a base station coupled to the carrier network. The base station is adapted to determine whether a subscriber unit is designated as having relatively high priority for accessing the carrier network; encode data for joint detection and transmit the encoded data to the subscriber unit if the subscriber unit is designated as having relatively high priority for accessing the carrier network; or transmit the data to the subscriber unit without encoding the data for joint detection if the subscriber unit is not designated as having relatively high priority for accessing the carrier network.

1. A wireless communication system, comprising:
 a carrier network; 
 a network application server coupled to the carrier network; and 
 a base station coupled to said carrier network, wherein said base station is configured to:
 determine that a first subscriber unit is designated as having relatively high priority for accessing said carrier network and that a second subscriber unit is not designated as having relatively high priority for accessing said carrier network; 
 encode data for joint detection and transmit said encoded data to said first subscriber unit; and 
 transmit data to said second subscriber unit without encoding said data for joint detection, 
 
 wherein the base station includes a proportional fair scheduler that increases a transfer data rate to the first subscriber unit to be higher than that of the second subscriber unit even though the first subscriber unit is located in a poorer radio frequency environment than the second subscriber unit. 
 
     
     
       2. The wireless communication system of  claim 1 , wherein said base station is further configured to receive a request for said data from said first or second subscriber unit. 
     
     
       3. The wireless communication system of  claim 2 , wherein said base station is further configured to forward said request for said data to said network application server by way of said carrier network. 
     
     
       4. The wireless communication system of  claim 3 , wherein said base station is further configured to receive said requested data from said network application server by way of said carrier network. 
     
     
       5. A method for a base station, comprising:
 determining that a first subscriber unit is designated as having relatively high priority for accessing a network and that a second subscriber unit is not designated as having relatively high priority for accessing said carrier network; 
 encoding data for joint detection by adding a preamble set of bits, known to the first subscriber unit, to the data and transmitting said encoded data to said first subscriber unit; and 
 transmitting data to said second subscriber unit without encoding said data for joint detection, 
 wherein the base station includes a proportional fair scheduler that increases a transfer data rate to the first subscriber unit to be higher than that of the second subscriber unit even though the first subscriber unit is located in a poorer radio frequency environment than the second subscriber unit. 
 
     
     
       6. The method of  claim 5 , further comprising receiving a request for said data from said first or second subscriber unit. 
     
     
       7. The method of  claim 6 , further comprising forwarding said request for said data to a network application server by way of said network. 
     
     
       8. The method of  claim 7 , further comprising receiving said data from said network application server by way of said network. 
     
     
       9. A base station, comprising:
 an RE interface; and 
 a processor configured to:
 determine that a first subscriber unit is designated as having relatively high priority for accessing a network and that a second subscriber unit is not designated as having relatively high priority for accessing said network; 
 encode data for joint detection and transmit said encoded data to said first subscriber unit by way of said RE interface; and 
 transmit data to said second subscriber unit without encoding said data for joint detection by way of said RE interface, 
 
 wherein the base station includes a proportional fair scheduler that increases a transfer data rate to the first subscriber unit to be higher than that of the second subscriber unit even though the first subscriber unit is located in a poorer radio frequency environment than the second subscriber unit. 
 
     
     
       10. The base station of  claim 9 , wherein said processor is further configured to receive a request for said data from said first or second subscriber unit by way of said RE interface. 
     
     
       11. The base station of  claim 10 , further comprising a network interface, and wherein said processor is further configured to forward said request for said data to a network application server by way of said network interface. 
     
     
       12. The base station of  claim 11 , wherein said processor is further configured to receive said requested data from said network application server by way of said network interface. 
     
     
       13. A computer readable medium storing one or more software modules to control a processor of a base station to:
 determine that a first subscriber unit is designated as having relatively high priority for accessing a network and that a second subscriber unit is not designated as having relatively high priority for accessing said network; 
 encode data for joint detection and transmit said encoded data to said subscriber unit; and 
 transmit said data to said subscriber unit without encoding said data for joint detection, 
 wherein the base station includes a proportional fair scheduler that increases a transfer data rate to the first subscriber unit to be higher than that of the second subscriber unit even though the first subscriber unit is located in a poorer radio frequency environment than the second subscriber unit. 
 
     
     
       14. The computer readable medium of  claim 13 , wherein said one or more software modules are configured to control said processor to receive a request for said data from said first or second subscriber unit. 
     
     
       15. The computer readable medium of  claim 14 , wherein said one or more software modules are configured to control said processor to forward said request for said data to a network application server. 
     
     
       16. The computer readable medium of  claim 15 , wherein said one or more software modules are configured to receive said requested data from said network application server. 
     
     
       17. A wireless communication system comprising:
 a plurality of base stations that transmit data to subscriber units in compliance with an 1xEV-DO protocol, wherein each of the plurality of base stations is configured to
 determine that a first subscriber unit is designated as having relatively high priority for accessing said carrier network and that a second subscriber unit is not designated as having relatively high priority for accessing said carrier network; 
 encode data for joint detection and transmit said encoded data to said first subscriber unit; and 
 transmit data to said second subscriber unit without encoding said data for joint detection, 
 
 wherein each of the plurality of the base stations includes a proportional fair scheduler that increases a transfer data rate to the first subscriber unit to be higher than that of the second subscriber unit even though the first subscriber unit is located in a poorer radio frequency environment than the second subscriber unit.
